Question

A drinking glass has a mass of 268.5 8. A 162 mL sample of milk is added to the glass. The mass of the glass with the milk is found to be 436.2 8. What is the density of the milk? Show your work to justify your answer.

Answer 1

Answer:

The density of the milk is 1.035 g/mL.

Explanation:

Density is determined dividing the mass of a substance by the volume it occupies.

density = mass (g) / volume (mL)

The mass, in this case, can be obtained subtracting the mass of the empity drinking glass (268.5 g) from the mass of the glass filled with milk (436.2 g).

density = (436.2 - 268.5) g / 162 mL

density = 1.035 g/mL
